It's not the end of the world if someone makes a phone call or takes a plane a couple times a year.
It's not the end of the world but it sure will cost the taxpayers a bit more money.
IT will cost the taxpayers less money.
Office space in the major metro ares are expensive.
In DC, even more so because the owners of the buildings (the US Government does not own many) jack up the costs because of who the tenant is/serves. The GSA does not negotiate very well for rent inside the Beltway.
Move departments outside of the DC metro area and the costs will drop.
They want to be close because the power factor is thought to rub off. Cloesr to the boss; more power you present.
with the exception of the State and Defense; all others could be moved out of DC close to any city that has direct flights 3-4 times a day to Dulles, BWI or Regan.
That would cover most every decent size city in the US and cut the floor space requirements in half.
Traffic gridlock would be reduced; most government employees would end up with a better lifestyle
